Nvidia stock was slumping Tuesday following a report about harsher curbs on chip sales to China ahead of a make-or-break quarterly earnings report. Shares of the semiconductor maker were down 2.7% to $126.

What happens with Nvidia matters for the entire U.S. stock market. The chip company has grown into the second-largest company on Wall Street, which means the stock’s movement carries more weight on the S&P 500 and other indexes than every company except Apple. The tech giant, based in Santa Clara, California, is now worth over $3 trillion.

Soundhound AI's (NASDAQ: SOUN) shares skyrocketed as much as 883% last year. However, the artificial intelligence (AI) stock is now down roughly 55% from its peak in late December. You can blame part of this decline on the Federal Reserve.
